Features

Fixed slits for high accuracy and repeatability

Fixed slits are a low cost alternative with excellent repeatability and are a good choice when only a few slit sizes are required. Avaialble in widths from 10 µm to 6.3 mm, they slide into the holders at all instrument ports, with the exception of those ports configured to mount a camera. The slit holders are installed by Newport during calibration of the instrument. The width and height cannot be adjusted but may be individually replaced with other slit sizes. These fixed slits are sold separately to allow customized choices based on the needs of the application. When ordering, be sure to purchase fixed slits of the same model (i.e. same size) for the input port and output port(s). Each of the fixed slits is mounted in a precision machined slide which is inserted into the 77294 or 77721 fixed slit holder. Contact us for more information.

Micrometer adjustable slits for flexibility and high throughput

A micrometer adjustable slit assembly provides versatility and convenience in changing resolution and throughput. They are ideal when the utmost accuracy and repeatability is required, especially at high resolution. These adjustable slits are continuously variable from fully closed to 3 mm width, with a narrowest practically achievable width of 4 µm. (Note that optimum spectral resolution for any monochromator is obtained with short, narrow slits.) A height adjustment slide allows variation in the height from 2 to 12 mm.

Motorized slits for computer control, automatic bandwidth selection

A motor driven slit assembly is offered for the MS257 which may be adjusted from 4 µm to 2 mm width in 2-µm steps. The slit width is controlled through the utility software, optional hand controller, optional TracQ Basic software or by using low level commands. An advantage of using motorized slits is that in addition to setting the slit widths individually, the software can be configured to an automatic bandpass setting. The software adjusts the slit widths to maintain the chosen bandpass as scans are performed using multiple gratings and either output port. If transitioning to a motorized slit assembly, factory recalibration service is recommended.
